Definitions

• Dyes known as oxidation dyes which are produced by oxidative coupling of a developer component with a coupling component, are preferred due to their intense colors and very good fastness.

• the hair dyestuffs are based upon oxidation dyes comprising bis-(2,4-diaminophenoxy)-alkanols of the formula ##STR1## wherein R is selected from the group consisting of the radicals ##STR2## or salts thereof with inorganic or organic acids, as coupling component, and, as developer component, one or more of the conventional developer substances used in oxidation hair dyes.
• oxidation dyes comprising bis-(2,4-diaminophenoxy)-alkanols of the formula ##STR1## wherein R is selected from the group consisting of the radicals ##STR2## or salts thereof with inorganic or organic acids, as coupling component, and, as developer component, one or more of the conventional developer substances used in oxidation hair dyes.
• Such hair dyestuffs can meet the above-mentioned requirements to an especially high degree and consequently represent especially valuable combinations in the area of oxidation hair dyes.
• novel compounds of Formula I which by themselves represent an aspect of the invention, can be prepared by known methods of organic chemistry in several steps.
• 2,4-dinitrophenol is reacted with the respective dibromoalkanol to form bis-(2,4-dinitrophenoxy)-alkanol.
• This compound is then converted in a second step into the desired bis-(2,4-diaminophenoxy)-alkanol by catalytic hydrogenation.
• the reaction scheme wherein R has the above meaning, is as follows: ##STR3##
• Additional aspects of the invention comprise the use of the bis-(2,4-diaminophenoxy)-alkanols of Formula I as such, or in the form of their salts with inorganic or organic acids, as coupling components in oxidation hair dyes as well as hair dyes that contain the bis-(2,4-diaminophenoxy)-alkanols of Formula I or their salts.
• the bis-(2,4-diaminophenoxy)-alkanols to be used as coupling components according to the invention can be used as such or in the form of their salts with inorganic or organic acids.

• they are also of special importance as nuancing components for the formation of the strongest possible shades that come close to the natural hair color nuances since difficulties frequently are encountered in the production of natural color nuances with the aid of blue coupling components.
• the coupling and developer components generally are used in approximately equimolar amounts. Although the equimolar use proves suitable, it is not disadvantageous to add the coupling component in a certain excess or deficiency.
